Can someone please remind me....
Our SBS 2008 server has a domain of, say, FRED.COM.
I have a user that works for another organisation on it so I want to promote his e-mail address over the default, user@FRED.COM to user@WILMA.COM.
When I try this is Exchange Management Colonsole/Recipient Configuration/Mailbox/User Name Properties/E-mail Addresses I get the message:
"Cannot remove the primary SMTP address 'user@FRED.COM'. Please promote another valid SMTP address before removing this one.
Can some kind soul remind me how to do this?
